Opus magnum or Great Work is an alchemical term for the process of creating the so-called philosopher's stone, attributed to ancient chemical processes that would allow the transformation of lead into gold. Alchemy as a proto-science, also sought to cure all diseases and discover the fountain of eternal youth. This is where the Myth begins. In its essence, the Alchemy would be a symbolic philosophical school that takes the resource of allegory to establish its objectives. Thus, transforming lead into gold means evolving the human being from his first stage, natural, to another spiritually superior through teachings that were leaving us Masters, or superior Gods in the past.
Likewise, the Philosopher's Stone, the elixir of youth, are no more than symbols of a much more psychological truth. In a hermetic way, alchemical treatises give instructions to obtain the greatest wisdom that a human being can reach, being the spiritual understanding among human beings some of its most important points for the final transmutation.
"At the beginning we unite, then we corrupt, we dissolve what has been corrupted, we purify what has been dissolved, we gather what has been purified and we solidify it. In this way man and woman become one. "
